I can ask if you want...but I absolutely became frozen when I heard those words out of our careers counsellor.
He's a pretty knowledgeable man and well informed.
I guess this gives him credibility??
But what do you think?
I think until he gives a substantiated reason besides 'they just will,' I'd not give it much thought (but then you could say the same about me, I'm a guy on the internet
)
It is important to understand where ATAR cut offs come from. They aren't arbitrary, they are supply versus demand. Universities have X places for their course, and so X people get in - The ATAR cut-off for a course from 2018 is just the lowest ATAR which got into the course. So the ATAR cut-off for a course for 2019 is impossible to know with certainty, because it depends who applies.
There are definitely expected patterns, and things like bonus points and guaranteed entry schemes, these are a bit different. But the system above is the core of how cut-offs work. So I can't think of anything that a blanket claim like that could be based on besides just intuition or guesswork, because it's purely based on the applicants in a given year! Unless he, based on his networks, expects certain courses to be increasing in popularity, or he is watching trends. But a high modality, blanket statement like "ATAR cut-offs will go up," seems a bit unfair to me
tl;dr - Go ask how he knows if it is seriously messing with you! But I would just try and forget it was said in the first place, it won't change how you should be preparing and working
